More MHD questions: JB+, Wastegate Raffle Fix

Curt · 05-20-2017, 10:17 PM

More noob MHD questions.

I currently have JB+ with AR catless DPs.

Am I supposed to remove the JB+ for flash? Can I just back up ECU with JB+ plugged in, then flash new mapping? Or would that brick JB+
With MHD, what stage/map should I purchase given my hardware?
Do I need to purchase a mapping if I just want to adjust wastegate rattle settings?
If I only adjust wastegate rattle settings, would that overwrite the JB+ config?

I flashed stock map with 0% rattle w/ jb+ still connected and got drastic improvements in mitigating wastegate noise, it feels like magic! Thanks to rich MHD devs for adding the rattle feature. Well worth $100.

Does the JB+ still add the psi for gains since i've flashed it? Feels slower and quieter but I'm assuming that's because of the rattle 'fix' mitigation

i heard someone here's giving away free wastegates?

I'm about 59 minutes from flashing my own rattle fix, but other than that, nothing to add to the discussion. Just killing time until my account activates and I can start my own thread. Still, the excitement!
